Mountain Bike Helmet Types

There are three main types of mountain bike helmets: full-face, open-face, and flip-up.

Full-face helmets are the most common type and are usually made out of plastic or composite materials. They are designed to protect all of the head area, including the eyes. Full-face helmets are not recommended for use in cold weather temperatures below 35 degrees Fahrenheit.

Open-face helmets are similar to full-face helmets, but they do not protect the eyes. Instead, they have a slot in the front that allows the rider to see out. Open-face helmets are recommended for use in colder weather temperatures below 35 degrees Fahrenheit.

Flip-up helmets are a newer type of helmet that is gaining popularity among mountain bikers. They are designed to protect both the head and the face. Flip-up helmets can be opened or closed with a simple flip of the lever. They are recommended for use in colder weather temperatures below 35 degrees Fahrenheit.
